Begonia plant named ‘Dobegicspflibutcup’

ABSTRACT

A new and distinct cultivar of  Begonia  plant named ‘Dobegicspflibutcup’, characterized by its relatively compact, upright to spreading and mounded plant habit; moderately vigorous growth habit; freely basal branching habit; dark greyed green-colored leaves; freely and continuously flowering habit; and medium-sized to large double and single flowers that are pale yellow in color.

Botanical designation: Begonia boliviensis.

Cultivar denomination: ‘DOBEGICSPFLIBUTCUP’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia boliviensis, and hereinafter referred to by the name ‘Dobegicspflibutcup’.

The new Begonia plant is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands. The objective of the breeding program was to develop new freely branching and flowering Begonia plants with large and attractive flowers and dark-colored leaves.

The new Begonia plant originated from a cross-pollination made by the Inventor during the autumn of 2013 of a selection of Begonia boliviensis identified as code designation BG08-000210-003, not patented, as the female, or seed, parent with a selection of Begonia boliviensis identified as code designation BG-1460, not patented, as the male, or pollen, parent. The new Begonia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Lier, The Netherlands during the spring of 2014.

Asexual reproduction of the new Begonia plant by vegetative tip cuttings in a controlled greenhouse environment in De Lier, The Netherlands since the spring of 2014 has shown that the unique features of this new Begonia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Begonia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Dobegicspflibutcup’. These characteristics in combination distinguish ‘Dobegicspflibutcup’ as a new and distinct Begonia plant:

-   -   1. Relatively compact, upright to spreading and mounded plant         habit.     -   2. Moderately vigorous growth habit.     -   3. Freely basal branching habit.     -   4. Dark greyed green-colored leaves.     -   5. Freely and continuously flowering habit.     -   6. Medium-sized to large double and single flowers that are pale         yellow in color.

Plants of the new Begonia can be compared to plants of the parent selections. In side-by-side comparisons, plants of the new Begonia differ primarily from plants of the parent selections in growth habit as plants of the new Begonia are more uniform than plants of the parent selections.

Plants of the new Begonia can be compared to plants of Begonia boliviensis ‘Beauvilia White’, not patented. In side-by-side comparisons, plants of the new Begonia differ primarily from plants of ‘Beauvilia White’ in the following characteristics:

-   -   1. Plants of the new Begonia have larger leaves than plants of         ‘Beauvilia White’.     -   2. Plants of the new Begonia have larger flowers than plants of         ‘Beauvilia White’.     -   3. Flowers of plants of the new Begonia face more upright and         outwardly than and not as downward as flowers of plants of         ‘Beauvilia White’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Begonia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Begonia plant. The photograph is a side perspective view of a typical flowering plant of ‘Dobegicspflibutcup’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photograph and following observations and measurements were grown in 12-cm containers during the summer in a glass-covered greenhouse in De Lier, The Netherlands. During the production of the plants, day temperatures ranged from 17° C. to 30° C., night temperatures ranged from 10° C. to 20° C. and minium light level was 135 watt/m². Plants were ten weeks old when the photograph and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
